Closure fastener, seal pin type



Patentecl Sept. 20, 1932 UN'E'ED STATESJ PATENT om=icrs EDWARD A. SWEELEY, OFALIEXANDRIA, VIRGINIA, A 1\TD NOR1VLAN cp. nrvpnnson, OF wnsnmeron, n1srmom or COLUMBIA GLOSURE FASTEN'ER, SEAL PIN TYPE Applicatioix filed. April 3,

cover to close an opening, and the pin sealed in its lockecl position by a metal sealing strip passed throngh the pin and held, say, by a leed seal, so that the pin can not be rernoved except by 1irst breaking the seal, the pin serv- 1o ing to seal the parts in their interlocked relation. The purpose of the present invention is to so form the seal-pin that it will have a wicler range of movement in a relatively small area, and possess a degree of flexibility that will avoicl oramping in move1nent of the pin into locking ancl unlocking positions, and insuring the easy entrance of the pin into its keepers.

T0 the accomplishment of the foregoing ancl snch other objects as may hereinafter appear the invention consists in the features hereinafter described and then songht to be clearly defined by the appended claims, reference being had to the accornpanying drawing forming a part hereof, and. in which,

Figure 1 is a perspective view of part of a car roof formed with a hatch-way opening ancl hingerl cover for the same, and showing the seal-pin applied to look the cover in a wholly or partially olosed position;

Fignre 2 is a perspeotive view of the sealpin, cletached.

In the drawing the numeral 1 designates part of a reight car provided with a hatohway frame 2 applied to en opening in the car roof and through which material may be supplied to the interior of the car, or instance a refrigerant, such as ice if the car be a refrigerating aar. The numeral 3 designates a door or cover attaohed by suitable hinges 4 to the car roof to wholly or partially formed with a series of openings 6 adaptecl to receive the seal-pin in a selected opening to look the cover in the position to whioh adjusted. The parts thus indicated may be of any desired, snitable construction. The improved seal-pin is designatel by the numeral 7, and comprises a base-shank 8, preferably 1931. Serial No. 527,586.

formed with an o-set portion 9 and adapted to be attaehed to a suitable metal base plate 10 bolted -or otherwise securecl to the hatch way cover by a pivot bolt passing through an opening 11 in the base-shank and into the base=plate 10 so that the base-shank may be rotatecl. To the base-shank 8, say to its ofiset portion 9, en angnlar hook-shaped. member 12 is swiveled, say by a pivot-pin 13, so that the hooked-shaped member may swing sicleways relatively to the rotatable baseshank 8, thus giving to the seal-pin a wider range of movement in a comparatively small area, with a more or less degree of flexure, as the jointed seal-pin will have two independent centers ofrotation, one being the pivot-bolt of the base-shank and the other the swivelor pivot 13 of the hook-shaped member onthe base-shank of the seal-pin and which provides a flexible-joint at the swivel points. The flexnre thus provided for the seal pin tends to prevent cramping action between the seal pin and the 'oooperating look- 1ng link where the pin passes through the openings in the link and associatecl parts. in movement of the seal pin into and out of lock ing.position. In practice, the base-platte 10 is formed with spaced apart perforated ears 14 and 15 at opposite ends of the plate be tween which the cooperatinglink 5may lie or locking the door in either a wholly closed or partially openecl position. With the door wholly closed the link 5 will lie between the ears 15and; the seal pin will pass through the registering openings in those ears and in the link 5 and thus the cover to the batchway opening will be locked in its closecl position. If the cover is to be locked in a partially openecl position as illustrated in F igure 1 of the drawing, the link 5 will lie between the ears 14 and the seal pin passed through close the hatch-way opening, and 5 designates a swinging link attached to the car roof and the registering openings of the ears 14 and the link 5 and the cover held in its partially openecl position asunder other constructions strong and eflicient in e and while its oost may be more than under other constrnctions the advantages gained o-set the extra oost.

The end of the angu1ar member 12 of the seal-pin will be made with a slot 16 to receive a meta1 strip (not shown) to whioh a lead sea1 Will be aflixed in awelI-known way to prevent wthdrawal of the pin until the sea1- is broken.

We have illustrated and describedfihepreferred details of the parts constituting the sea1 pn but changes may be made ther ein without departing from the scope of the invention as sought to be defined in the following claims. Nor is the seal pin confined in its use to the other cooperatng elements selected for purposesof illustrating one ernbodiment of the inventon as it may be used under ether conditions and where the sealpin may possess the functionaifeatnres em bodied in the seal-pn as herein descrbed.

Having described om inventon and set 0rqh its merits whatwe claim is 1. A seal-pin compiising a pivotal shank member, and a second member pivotally mounted on the shank memoer and having its free end extending in a p]lane substantially at Igh; angles to the axis of both pivots,

pivotally m0unted member in a projected locking position.

5. A fastener embodyng a seal-pin comprsing a pivotal shank-member and a second member pvotally mounted on the shank member,:each member being free tooturn on its independent axis in movement ofthe free end of one member into position fox engagement with a cooperative lo ckng member and means for securing the pivotally mounted member ina"projected lockng position.

6. A fastener embodying a flexibly jointed' two-part pivotally mounted Seal-pin member, ea c h part having anindependent axs of r0- tation and means f0r securng the sea1 pin member in a 1ocking position.

In testimony whereof we afix our signatures.
